Not Even Wrong
While I was away on vacation, the big news in physics was the BICEP2 result on B-modes in the CMB. Maybe it’s just as well I wasn’t available to blog about this, since inflation and cosmology aren’t at all my field of expertise. Now that some of the dust has settled from the media blitz though, I do think it’s worth while to write something here, since there are some aspects of the story where the media coverage could use some extra perspective. First of all, there’s the obligatory caveat about this result not being definitive, which most coverage by scientists has included. To my non-expert eye, looking at the main graph reproduced everywhere, if you subtract the gravitational lensing background you get something which is much larger at higher values of l than it is supposed to be if it were coming from primordial gravitational waves. For the implications of this kind of confirmation of inflation, one obvious question is what it means for string theory.

Forensic Science Central – Forensic Anthropology Forensic Anthropology Forensic anthropology combines the theories and methods of anthropology, osteology and archaeology with legal investigations. The role of the forensic anthropologist can be varied, including aiding in the collection and analysis of human remains, the identification of victims beyond recognition, the estimation of time since death, and the establishment of injuries and potentially cause of death. Pontecorvo–Maki–Nakagawa–Sakata matrix In particle physics, the Pontecorvo–Maki–Nakagawa–Sakata matrix (PMNS matrix), Maki–Nakagawa–Sakata matrix (MNS matrix), lepton mixing matrix, or neutrino mixing matrix, is a unitary matrix[note 1] which contains information on the mismatch of quantum states of leptons when they propagate freely and when they take part in the weak interactions. It is important in the understanding of neutrino oscillations. This matrix was introduced in 1962 by Ziro Maki, Masami Nakagawa and Shoichi Sakata,[1] to explain the neutrino oscillations predicted by Bruno Pontecorvo.[2][3]

FQXi FQXb (bio)By WILLIAM OREM • Mar. 23, 2014 @ 21:39 GMT Everyone is talking this week about the dramatic confirmation of inflationary theory: those first-instant gravitational waves whose details may even point--being, if you will, quantum phenomena that went suddenly ultra-macroscopic--toward the correct way to unify QM and GR. I myself have been musing on rather astonishing work in another field. Will you pardon the intrusion if we talk a little bit about biology? Recently the big news there was released: an unprepossessing experiment involving a weak acid bath showed it's possible to revert mature, differentiated cells to a stem cell state, allowing for the prospect of wholesale repurposing. The surprise wasn't that reversion (or conversion from one mature type into another) can be done--genetics work in that direction took home a Nobel in 2012--but that it can be done so simply.

The so-called "holy grail" of mathematics may have just been found. Shinichi Mochizuki, a professor at the Research Institute for Mathematical Sciences at Kyoto University, released a 500-page proof of the abc conjecture in number theory which involves the relationship between prime numbers, which I will attempt to describe as succinctly as possible below. A lot of open theory on prime numbers is based on the abc conjecture.

Technicolor (physics) Technicolor theories are models of physics beyond the standard model that address electroweak gauge symmetry breaking, the mechanism through which W and Z bosons acquire masses. Early technicolor theories were modelled on quantum chromodynamics (QCD), the "color" theory of the strong nuclear force, which inspired their name. In order to produce quark and lepton masses, technicolor has to be "extended" by additional gauge interactions.

Scientist Prove DNA Can Be Reprogrammed by Words and Frequencies digg By Grazyna Fosar and Franz Bludorf THE HUMAN DNA IS A BIOLOGICAL INTERNET and superior in many aspects to the artificial one. Russian scientific research directly or indirectly explains phenomena such as clairvoyance, intuition, spontaneous and remote acts of healing, self healing, affirmation techniques, unusual light/auras around people (namely spiritual masters), mind’s influence on weather patterns and much more.

Pontryagin duality In mathematics, specifically in harmonic analysis and the theory of topological groups, Pontryagin duality explains the general properties of the Fourier transform on locally compact groups, such as R, the circle, or finite cyclic groups. The Pontryagin duality theorem itself states that locally compact groups identify naturally with their bidual. The subject is named after Lev Semenovich Pontryagin who laid down the foundations for the theory of locally compact abelian groups and their duality during his early mathematical works in 1934.

Joseph-Louis Lagrange Joseph-Louis Lagrange (born Giuseppe Lodovico Lagrangia [1][2][3] (also reported as Giuseppe Luigi Lagrangia [4]), 25 January 1736 in Turin, Piedmont; died 10 April 1813 in Paris) was an Italian Enlightenment Era mathematician and astronomer. He made significant contributions to the fields of analysis, number theory, and both classical and celestial mechanics. In 1766, on the recommendation of Euler and d'Alembert, Lagrange succeeded Euler as the director of mathematics at the Prussian Academy of Sciences in Berlin, Prussia, where he stayed for over twenty years, producing volumes of work and winning several prizes of the French Academy of Sciences. Cabibbo–Kobayashi–Maskawa matrix The matrix[edit] A pictorial representation of the six quarks' decay modes, with mass increasing from left to right. In 1963, Nicola Cabibbo introduced the Cabibbo angle (θc) to preserve the universality of the weak interaction.[1] Cabibbo was inspired by previous work by Murray Gell-Mann and Maurice Lévy,[2] on the effectively rotated nonstrange and strange vector and axial weak currents, which he references.[3]

24,000-Year-Old Siberian Boy Sheds New Light on Origins of Native Americans The genome sequence of a 24,000-year-old young Siberian individual found in Russia shows that 14 to 38 percent of modern Native American’s ancestry came from this youngster’s gene pool, suggesting First Americans came directly from Siberia. The new study shows that ancestors of Native Americans migrated to the Americas from Siberia and not directly from Europe. Painting by G. Mülzel. The Paleolithic skeleton was first discovered in the late 1920s near the village of Mal’ta in south-central Siberia, and since then it has been referred to as the Mal’ta child because until this DNA study the biological sex of the skeleton was unknown. “Now we can say with confidence that this individual was a male,” said Dr Kelly Graf from Texas A&M University, a co-author of the paper published in Nature.

Fredkin finite nature hypothesis In digital physics, the Fredkin Finite Nature Hypothesis states that ultimately all quantities of physics, including space and time, are discrete and finite. All measurable physical quantities arise from some Planck scale substrate for multiverse information processing. Also, the amount of information in any small volume of spacetime will be finite and equal to a small number of possibilities.[1] Conceptions[edit] Stephen Wolfram in A New Kind of Science, Chapter 9, considered the possibility that energy and spacetime might be secondary derivations from an informational substrate underlying the Planck scale.
